Mitochondrial instability in the FANCGR22P cell causes the transcriptional down-regulation of mitochondrial iron-sulphur cluster biogenesis protein Frataxin (FXN) and resulting iron deficiency of FA protein FANCJ, an iron-sulphur containing helicase involved in DNA repair.


Despite of DNA repair ability the Fanconi anemia mutant protein FANCGR22P destabilizes mitochondria and leads to genomic instability via FANCJ helicase . Preprint from bioRxiv, 15 Jan 2020
